INICnet 150 Mbps Intelligent Network Interface Controller
OS81118 is available for following applications
• INICnet 150 Coaxial Networks (cPHY)
• INICnet 150 Optical Networks (oPHY)
General Description
The OS81118 is a single network port Intelligent Network Interface Controller
(INIC) for the 150 Mbps INICnet Network with support for both optical physical
layers (oPHY) and coaxial (coax) physical layers (cPHY) that can efficiently
handle audio, video, packet, and control data for infotainment and Advanced
Driver Assistance Systems (ADAS).
The cPHY supports point-to-point connections with full-duplex communication, reducing system costs through the reduced number of cables and connectors that are necessary to connect the single devices. The OS81118 can be used with the OS81119 to form a daisy-chain network topology. The classic ring topology with dual-simplex communication is supported by oPHY and cPHY.
The OS81118 offers industry standard interfaces to peripheral components: I2C, I2S (and similar formats) audio streaming ports, MediaLB, SPI, and USB2.0. The MediaLB and USB interfaces support all data types (stream, packet, control) simplifying connections for a wide variety of applications. INICs include a powerful stream-data routing engine that links the application ports to network channels and allows dynamic reconfiguration.
Microchip’s Unified Centralized Network Stack (UNICENS) supports establishing of all network connected data resources from one point in the network, enabling simple, yet full featured network connections. Software support for interfacing to the INIC’s data I/O ports in Linux applications is provided by the native driver included in Automotive Grade Linux. A QNX driver for the USB interface is available. For MOST implementations, a variety of software support is available.
INICs encapsulate all low-level network-management functions relieving the External Host Controller (EHC) from the burden of managing real-time network tasks. INICs monitor and manage a variety of network conditions to support robust network functionality and fault detection and recovery. A built-in watchdog protects the network from EHC faults. INIC protection mode prevents application malfunctions from influencing the integrity of the network and the system. INICs also provide support for device power management.
Remote control functionality is supported obviating the need for an EHC in certain “slim” applications. The INIC can be fully configured and managed through the network. Peripheral components can be configured / monitored via I2C tunneling.
Optionally IP-based system management can be supported via the Ethernet packet channel providing seamless integration of the multimedia network with Ethernet networking in other vehicle domains.
